Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting mechanism for lighting covers and the like.

A lighting fixture using a conventional mounting mechanism is shown in FIG. That is, in this lighting device, a hole 3 is formed in the cover frame 2 of the lighting cover 1, a ring 4 is passed through the hole 3, and the ring portion 6 of the tight spring 5 is freely hung on the ring 4, while a hole 3 is formed on the inner surface of the device body 7. , attach the spring receiving piece 9 with the C-shaped cutout 8, which is a slit, and attach the spring receiving piece 9 to the both ends of the tight spring 5 as shown in FIG.
are narrowly closed together and the tip engaging part 11 is hung on the edge of the C-shaped notch 8, and in this state, the cover frame 2 is attached to the instrument main body 7.
The cover 1 is attached to the instrument body 7 by pressing against the
It is to be worn. In this case, the tight spring 5
The action of works as follows. That is, in the state shown in FIG. 2, the cover frame 2 is not attracted to the appliance main body 7 with both end legs 10 bent and is in a temporarily suspended state, so that the lamp can be replaced using this. FIG. 3 shows a state in which the cover frame 2 is pushed up slightly, and the legs 10 at both ends of the tightening spring 5 are gradually expanded and when the angle exceeds a certain angle, a pulling force is generated and the fourth
When the state shown in the figure is reached, the cover frame 2 is automatically drawn to the instrument body 7. Conversely, if the cover frame 2 is forcibly pulled down, it will be in the temporarily suspended state shown in FIG. Further, when removing the cover frame 2, it is done by bending and removing the tight spring 5 from the C-shaped notch 8 of the spring receiving piece 9.

Next, the lighting equipment shown in FIGS. 5 and 6 is one in which the spring receiving piece 9 is provided on the cover 1 and the tightening spring 5 is provided on the equipment main body 7 side by the same means as described above, and the lighting equipment shown in FIG. The action of the tightening spring 5 is the same as described above, except that the mounting mechanism stands in the opposite relationship. In this case, the cover 1 needs to be deep enough to accommodate the tight spring 5.

However, the above attachment mechanism has the following drawbacks. That is, (1) When hanging the tight spring 5 on the spring receiving piece 9, it is necessary to bend the tight spring 5 by hand, which is troublesome.

(2) If you try to bend the tight spring 5 by hand and hang it on the spring receiver piece 9, if you make a mistake and flip the spring,
The tip engaging portion 11 of the bent spring may hit the cover 1 made of plastic or glass, damaging the cover 1 or hitting the hand during operation, which is dangerous.

(3) If the spring receiving piece 9 is on the side of the cover 1, when attempting to attach the cover 1 after attaching the appliance body 7 to the ceiling, it is difficult to hang the tight spring 5 because the spring receiving piece 9 is not visible.

Therefore, an object of the present invention is to provide a mounting mechanism that allows a lighting cover or the like to be mounted easily and safely.

An embodiment of this invention is shown in FIGS. 7 and 8. That is, in this mounting mechanism, a spring receiving piece 13 having a slit 12, which is a C-shaped notch, is provided on a mounting member 1, which is a cover, and a ring of a tight spring 5 is provided in the center of the slit 12. A support piece 14 that supports the part 6 in a protruding state from the upper surface of the mounting member 1 is cut and bent, and a hook 15 and a ring are used to hang the ring part 6 of the spring 5 on the member 7 to be attached, which is an example of an instrument body. By cutting and raising the retaining piece 16 that prevents the part 6 from coming off, the spring 5 can be tightened.
A hook 17 is attached with a gap H formed in a direction perpendicular to the direction of movement.

FIG. 9 shows a state in which the tight spring 5 is attached to the spring receiving piece 13. That is, the ring part 6 is made to face the slit 12 as shown by arrow A, the outer bottom surface of the ring part 6 is hooked onto the support piece 14, and the ring part 6 is placed in a vertical position as shown in FIG. You can talk about it). In this state, both end legs 10 of the tight spring 5 have slits 12.
The ring part 6 is attached to the support piece 1 by elastically contacting both end edges of the support piece 1.
At the same time, the ring part 6 becomes in a state of protruding from the upper surface of the mounting member 1. (This is the packaged state).
Further, when the ring part 6 is pulled up further, the tip engaging part 11 is engaged with both ends of the slit 12, and a stable state is achieved. FIG. 11 shows a state in which the attachment member 1 is brought close to the member to be attached 7 and the loop portion 6 is hung on the hook 15, and FIG. 12 shows a state in which the attachment member 1 is temporarily suspended from this state. Furthermore, FIG. 13 shows a state in which the mounting member 1 is pushed up from the temporarily suspended state to the mounted state, and at this time, the ring portion 6 is tilted inwardly from the instrument body 7 by the pull-out tab 16 and pulled out. It also plays the role of holding down the ring part 6 together with the hook 15.
Moreover, when the attachment member 1 is removed from the member to be attached 7, it is done by removing the ring portion 6 from the temporarily suspended state using the gap H.

A tight spring having a ring portion 6 formed in the center and tip engaging portions formed at the tips of both end legs, and a slit through which the both end legs of the tight spring are inserted and sandwiched against the expansion spring action of the tight spring. and a mounting member provided with a support piece in the center of the slit to prevent the loop of the tight spring from coming off, and a gap through which a part of the loop of the tight spring is inserted, which is aligned with the operating direction of the tight spring. Since the attached member has a hook portion formed in a perpendicular direction, the following effects can be obtained. That is, when attaching and detaching the tight spring, the ring portion can be safely and easily attached and detached from the gap without receiving resistance from the spring force of the tight spring. Furthermore, since the support piece is provided at the center of the slit, even if the tight spring is removed from the attached member, the tight spring will not come off from the mounting member.
